Jah has an amazing place to stay. It's really hard to find a well-decorated private room like Jah's in the center of the city. It's also really affordable compared to the service (like the amenities and friendliness). I didn't get a chance to meet Jah in person but I met her brother and her part-time who are very nice to help us find private transportation as well as recommend us a good place to hang out. If you are a shopping addict, the location is pretty near from shopping malls such as Platinum, MBK, and Siam, so you can spend your time visiting the mall while staying at Jah's place. There are a lot of street food at the end of the road out of her place such as Pad Thai, Noodles, Chicken, etc., very near to 711 as well.
Wifi is decent and well. The room is a little bit stuffy when the air conditioner is turned off because the windows are kept closed. But there'll always a room to improve, right? If your belongings are quite a lot you need to make sure that you are not on the 4th Floor because the stairs are a little bit tiny. Jah's place provides a hot shower, so you can take shower whenever you want to. Enough space for 2 people. Very recommended place to stay when visiting Bangkok!
